This application claims the benefit of Korean Patent Application No. 10-2009-0109872, filed on Nov. 13, 2009, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
1. Field
Aspects relate to an image forming apparatus which is capable of saving resources and a resource saving mode control method thereof, and more particularly, to an image forming apparatus which provides a suggestion option to save resources and a control method thereof.
2. Description of the Related Art
As the use of computers increases, peripherals for the computers are increasingly used. Representative examples of computer peripherals are printers, scanners, copiers, and multifunction peripherals which incorporate at least two functions of the aforementioned devices. In a printing environment, the more a user uses consumables, the more benefit a manufacturer obtains. However, in a recent printing environment, an increase of cost caused by use of consumables is a negative factor that affects profit of a business. Also, an eco-friendly factor has been increasingly introduced in the printing environment as laws protecting the environment and consumer awareness have become more common.
However, a related-art eco-friendly technique treats only a simple function such as a toner saver and allows only a restrictive use such that only a function that is already registered by an administrator is used independent of a user's wish. Therefore, the related-art eco-friendly technique does not derive an efficient use and an eco feature forcedly used in an actual situation does not derive active participation from a user, thereby causing inconvenience to the user. Particularly, in the case of a commonly used device such as a multifunction peripheral, user's participation is low and a user does not show a strong attachment to the process. An important factor of such a device from a standpoint of suppliers is to reduce a cost by saving consumables and foster user's participation to maintain the device's function. Also, from a user's standpoint, there is a demand for a method providing a suitable eco interface to derive active participation from a user without making the user feel passive participation, and providing satisfaction for the active participation and also using a device efficiently.
Accordingly, it is an aspect to provide an image forming apparatus which provides a suggestion option saving resources and a resource saving mode control method thereof.
Additional aspects and/or advantages will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the invention.
The foregoing and/or other aspects are achieved by providing a control method of an image forming apparatus which is connectable to an external apparatus, supports a resource saving mode, and outputs document data, the control method including: selecting the document data to be output, selecting an output option from among output options, to be applied to the selected document data, comparing a resource saving value corresponding to the output option to be applied to the document data and a resource saving set value which is pre-set in the image forming apparatus, displaying at least one suggestion option saving resources of the document data according to a result of comparing, and selecting one of the displayed suggestion options and outputting the document data according to the selected option.

Reference will now be made in detail to the present embodiments, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the embodiments by referring to the figures.
The image forming apparatus 100 can be connected to an external apparatus, supports a resource saving mode, and has a function of outputting document data, and it is realized as a printer, a scanner, a copier, and a multifunction peripheral incorporating at least two functions of the aforementioned devices.
The communication interface 110 supports data communication with an external apparatus (not shown) through a network. For example, the communication interface 110 supports a digital living network alliance (DLNA) network, a local area network (LAN), or the internet.
The input unit 120 has a plurality of function keys which enable a user to set or select various functions supported by the image forming apparatus 100, and receives a command from the user. Also, the input unit 120 is realized as a device realizing input and output simultaneously, such as a touch pad. In particular, the input unit 120 receives a user command to apply a resource saving mode. For example, the input unit 120 receives a user command to select an output option which will be applied to document data to be output. The document data to be output, recited herein, may include at least one of pre-stored document data, printing data received from an external apparatus connected to the image forming apparatus 100, received fax data, received E-mail, a document to be copied, or a document to be scanned.
The display unit 130 displays information provided by the image forming apparatus 100, a status of a job which is being in progress in the image forming apparatus 100 and a result thereof. A user identifies diverse printing jobs of the image forming apparatus 100 and controls managing the jobs through the display unit 120. More specifically, the display unit 130 may be controlled by the controller 150, which will be described below, to display at least one suggestion option for saving resources. The suggestion option recited herein may be at least one output option that satisfies a pre-set resource saving set value or at least one combination of the at least one output option. However, it is understood that a resource saving set value may be changed by the user. Also, the output option may include at least one of options for saving resources, that is, a duplex output option, a multiple-pages-per-sheet output option, a size reduction printing option, a monochrome output option, a toner saving/density control option, a printing quality/resolution option, a batch output option, a blank page deletion option, and a background deletion option. These output options may be set as a default value by a manufacturer of the image forming apparatus 100 and may be upgraded using a program. The printing quality/resolution option is to determine a physical resolution for printing and is to change the resolution by changing the number of dots used per 1 inch (dpi). The other options are well-known to an ordinary skilled person in the related art and thus detailed description thereof is omitted. A screen to display the suggestion option may be displayed as a separate window from a currently displayed screen.
The display unit 130 may be controlled by the controller 150 to display a resource saving set value in the form of a scroll bar (or an eco slider). The form of a scroll bar recited herein refers to a form that can adjust a resource saving set value using a cursor, and is similar to a slider form. Also, the display unit 130 may be controlled by the controller 120 to display a resource saving rate in the form of a percentage (%). Also, a resource saving set value that can be presented as a suggestion option for an output document (or a job) may be set in the form of a level (for example, a pre-set percentage unit: 10%, 20%, 30%). However, this should not be considered as limiting and any form can be applied that can represent a saving rate. Also, the display unit 130 may be controlled by the controller 150 to display a resource saving rate in the form of a graph. The graph may be changed according to a change in the resource saving rate. The display unit 130 may be realized as a touch screen incorporated in the input unit 120.
The storage unit 140 stores a unit cost calculating a cost corresponding to the resource saving set value. Also, the storage unit 140 may store CO2 emission per unit, for example, may store CO2 emission per sheet if each option is applied. Also, the storage unit 140 may store related data so as to separately apply different categories such as paper saving, toner saving, and energy saving categories. Also, the storage unit 140 may store output options (for example, a toner saving option or a resolution option) corresponding to a certain image forming job (for example, a printing job) and attribute values applicable to the output options (for example, an output density level and a resolution level). Also, the storage unit 140 may store a suggestion option list corresponding to a resource saving set value in a resource saving mode. The storage unit 140 may be realized as an internal storage medium or an external storage medium of the image forming apparatus 100, such as a removable disk including a USB memory, a storage medium connected to a host, and a web server linked through a network.
The controller 150 controls operation of the respective components of the image forming apparatus 100 according to pre-stored diverse programs. In particular, the controller 150 may compare a resource saving value which corresponds to an output option to be applied to target document data and a resource saving set value which is in the image forming apparatus 100, and control the display unit 130 to display at least one suggestion option saving resources of the document data according to a result of comparison.
Also, the controller 150 may control the output unit 160 to output the document data according to a suggestion option that is selected from among the suggestion options displayed on the display unit 130. Also, if the resource saving value corresponding to the output option to be applied to the document data is less than the resource saving set value, the controller 150 may control the suggestion option to be displayed. On the other hand, if the resource saving value corresponding to the output option to be applied to the document data is greater than or equal to the resource saving set value, the controller 150 may control the job to be performed without displaying the suggestion option. Also, in some situation, even if the resource saving value corresponding to the output option to be applied to the document data is greater than or equal to the resource saving set value, the controller 150 may control related information to be displayed so that a user can check the information. The resource saving value corresponding to the output option to be applied to the document data, recited herein, refers to a resource saving value that can be obtained with respect to the document data in a currently set output environment. The resource saving set value may refer to a value that is set as a default value by an administrator according to an office policy, for example.
Also, the controller 150 may calculate the resource saving value which corresponds to the output option to be applied to the document data. Also, the controller 150 may calculate and display the resource saving value, which corresponds to the output option to be applied to the document data, and the resource saving set value, as a saving cost or CO2 emission. If a user command to change the resource saving set value is input by manipulating a scroll bar or inputting a numerical value, the controller 150 may display a suggestion option that corresponds to a resource saving set value changed according to the user command. The suggestion option to be applied to the document data may be set by the controller 150. However, the suggestion option may be set as a default value or may be edited by the user in some situation. Also, the controller 120 may calculate the resource saving value corresponding to the output option to be applied to the document data and the pre-set resource saving set value as a cost or CO2 emission using a stored unit cost table.
The output unit 160 outputs the document data according to a suggestion option that is selected from among the suggestion options displayed on the display unit 130. The output unit 160 converts the document data into image data which can be output, and prints the image data on a recording medium. For example, in the case of a laser type image forming apparatus, a surface of an organic photoconductive (OPC) drum (not shown) is electrically charged by a charging unit (not shown) and a latent image is formed on a charged area by a laser scanning unit (LSU) (not shown). The latent image is developed by a developing unit (not shown) and a toner is attached to the latent image. The toner image is transferred to paper by a transferring unit (not shown) and is fused to the paper by a fusing unit (not shown). However, this is merely an example and the embodiment can be applied to an ink-jet type image forming apparatus. Although applying the resource saving mode is controlled by the components included in the image forming apparatus 100 in the above embodiment, all of the functions described above may be controlled by a printer driver (not shown) or an application (not shown) provided in a host device (not shown) connected to the image forming apparatus 100. This will be explained with reference to
A printing control terminal apparatus 200 illustrated in
A communication interface 210 is connected to at least one image forming apparatus and provides printing data which has been converted with respect to a printing job (converted document data and selected output option information) to the image forming apparatus. More specifically, the communication interface 210 is designed to connect the printing control terminal apparatus 200 to the image forming apparatus and may be realized as a parallel port, a universal serial bus (USB) port, or a wireless module.
An input unit 220 includes a plurality of function keys that enable a user to set or select diverse functions supported by the printing control terminal apparatus 200, and may be realized as a device realizing input and output simultaneously such as a touch pad, or a mouse. Using the input unit 220, the user selects document data to be output through the image forming apparatus connected to the printing control terminal apparatus 200 via the communication interface 210, and selects an output option to be applied to the selected document data.
A display unit 230 displays information provided by the printing control terminal apparatus 200. In particular, the display unit 230 may display at least one suggestion option saving resources in outputting the selected document data. Also, the information displayed on the display unit 230 and its display format are the same as those of the display unit 130 of the image forming apparatus 100 of
A storage unit 240 may store information about the image forming apparatus 100 which is received from the communication interface 210. The storage unit 240 may temporarily store printing data which is generated by a printer driver 250 which will be described below, and may pre-store a script which stores a printing option supported by each image forming apparatus and information about a supported print language.
The printer driver 250 includes a plurality of drivers corresponding to a plurality of languages and performs printing jobs with respect to a plurality of image forming apparatus which operate in different languages. More specifically, if a user wishes to print a document created by an application, the printer driver 250 creates printing data using a print language which is perceivable by an image forming apparatus the user wishes to use to print the document. A controller 260 controls a component which is necessary to perform a printing job using the printer driver 250 according to an output option selected through the image forming apparatus. More specifically, the controller 260 compares a resource saving value which corresponds to an output option to be applied to document data and a resource saving set value which is in the image forming apparatus, and controls the display unit 230 to display at least one suggestion option saving resources of the document data according to a result of comparison. Also, if the resource saving value corresponding to the output option to be applied to the document data is less than the resource saving set value, the controller 260 may control the display unit 230 to display a suggestion option. The suggestion option may be at least one output option that satisfies the resource saving set value or a combination of the at least one output options. Also, the printing control terminal apparatus 200 can perform the configuration of the image forming apparatus 100 of
The image forming apparatus 100 adopts the same configuration as that of
The image forming apparatus 100 may be connected to the plurality of external terminal apparatuses 10 to 30 through the network 40. The network 40 recited herein may be realized as a DLNA network, a LAN, or the internet. More specifically, the communication interface 110 may communicate with the communication interface of each of the plurality of external terminal apparatuses 10 to 30 through a DLNA network, a LAN, or the Internet.
At least one of the external terminal apparatuses 10 to 30 may be realized as an administration server. The administration server may be a network administrator of an office. The administration server may set the resource saving set value as a default value. However, the resource saving set value may be set to be changed by the user. Also, the administration server may set only some of diverse output options to be applied and the other options not to be applied. Also, accessibility of the output option to the user may be set or changed by the administration server. Also, an attribute value applied to the at least one output option may be set as a default value. Also, the administration server may set the resource saving set value, which has been set as a default value, to be changed if a password is authenticated. Also, the administration server may set a different resource saving set value for each image forming job and also may set the resource saving set value to be changed through a different password authentication procedure. Also, the administration server may set a different password for each option that is applied when the resource saving mode is selected. The administration server may control setting/changing a resource saving rate and setting/changing a password, using a network server or an embedded web server, or using the image forming apparatus 100.
At least one of the plurality of external terminal apparatuses 10 to 30 may be the printing control terminal apparatus 200 illustrated in

Each suggestion option may include a cost that can be saved for a corresponding image forming job. In this case, the resource saving set value or cost corresponding to the suggested option does not have to be identical to the resource saving set value or cost, and falls within a pre-set error range. If the pre-set resource saving set value is 100%, the eco suggestion function cannot be presented and a message “Printing Not Allowed” or “No Suggestion Option Exists” may be displayed. Also, even when the set resource saving rate is not 100%, if a suggestion solution cannot be presented, the same message as that of the resource saving rate of 100% may be displayed. Also, the eco suggestion screen 500 may display an eco apply button 50 to apply the suggestion option selected by the user.

According to an embodiment illustrated in
Referring to
According to a control method of an image forming apparatus which is connectable to an external apparatus, supports a resource saving mode, and outputs document data, document data to be output is selected and an output option to be applied to the selected document data is selected (S810). Next, a resource saving value corresponding to the output option to be applied to the document data is compared with a resource saving set value which is pre-set in the image forming apparatus, and at least one suggestion option saving resources of the document data is displayed according to a result of comparison (S820). One of the suggestion options is selected and the document data is output (S830). Detailed configuration and embodiment of each operation are described above and thus are omitted.
An effect incurring when a resource saving mode is activated in an image forming apparatus, for example, saving details of the image forming apparatus are presented to the administrator or the user (or presented as a report) in comparison with those of a general image forming apparatus. The saving details for each job and each quarter, month, and year are provided to the administrator or the user on a real time basis. Accordingly, the administrator or the user can obtain a feedback resulting from application of a resource saving function.
According to the diverse exemplary embodiments described above, active participation of a user is derived so that a negative effect caused by passive participation when a resource saving mode is applied can be offset and also an administrator can obtain a cost effect by saving consumables. From a standpoint of a related-product seller, there is an effect of relieving environmental consumption.
Although a few embodiments have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
